家犬最早可能是作为宠物被饲养的,而后成为古人狩猎的助手,同时在战争、看家护院、随葬和祭祀中发挥过特殊的作用。从整体上看,家犬作为宠物的作用是始终存在的。但是,除了特定的时期和地区之外,家犬基本上并非是古代人类依赖的肉食来源。 Dogs may have been raised as pets as early as possible and later become ancillary to ancient people’s hunting while playing a special role in wars, house nurseries, funerals and rituals. As a whole, the dog’s role as a pet is always there. However, except for specific periods and regions, domesticated dogs are basically not the sources of meat that ancient humans rely on.
